GUN Project Plan

The GNU Project was launched in 1984 by Richard Stallman, a famous hacker. GNU received support from the FSF for Free Software Foundation, which is also the main source of funds for GNU, the purpose is to establish a free UNIX system. The basic principle is source code sharing and idea sharing.
GNU is the abbreviation of "GNU's Not Unix.
The Chinese Translation of GNU [nu:, nju:] is karma ). Therefore, the GNU mark is like this. Remember that he is a horned horse, not a ox, or anything else. Come on, joke!

LNUX development history and Linus Torvalds
Linux core author Linus Torvalds

Linux was released by Linus Torvalds at Helsinki University in Finland in October 1991. Linux is a clone of a UNIX operating system.
Linux kernel + GNU utilities = open source, UNIX-like operating system
Operating Systems with only the kernel and no application software cannot be used. Therefore, many companies or organizations organize the kernel, source code, and related applications into a complete operating system, allows general users to easily install and use Linux, which is the so-called release version distribution ).

Of course, our REDHAT

REDHAT was created by Bob Young Marc Ewing in 1994 and is one of the world's largest open source code companies.

The desktop version is up to 9 and 0, which is also out of print. From then on, REDHAT will focus on the server version. I didn't invest too much in the desktop. Fedora Core was developed by REDHAT in cooperation with the open-source community. It is not owned by REDHAT. The Enterprise Edition Enterprise 5.1 will be used for teaching and will be released in March October.
